Magnetic behavior of Co ions in the exotic spin-chain compound,Ca3Co2O6, from 59Co NMR studies

E. V. Sampathkumaran, N. Fujiwara, S. Rayaprol +2

We have performed field-swept 59Co NMR measurements on the 'exotic' spin-chain material, Ca3Co2O6, crystallizing in K4CdCl6-type rhombohedral structure, believed to exhibit two mag…

Superconductivity of the $S r_{2} C a_{12} C u_{24} O_{41}$ spin ladder system: Are the superconducting pairing and the spin-gap formation of the same origin?

Naoki Fujiwara

Pressure-induced superconductivity in a spin-ladder cuprate Sr $_{2}$ Ca $_{12}$ Cu $_{24}$ O $_{41}$ has not been studied on a microscopic level so far although the superconductivity was a…
